The invention discloses sunglasses used for identifying the distraction of a driver and a method and belongs to the field of traffic safety. The sunglasses comprise a sunglasses sub-system and a vehicle-mounted sub-system; the motion information of the head of the driver is collected through a six-axis accelerometer embedded in the nose bridge of a sunglasses support; and data transmission is carried out through a Bluetooth module. According to the method, whether the driver wears the sunglasses or not is judged according to the data of the six-axis accelerometer; the data range of the six-axis accelerometer in a non-distraction driving state is calibrated; a microprocessor performs driving distraction early warning according to the data of a GPS; and on the basis of the data of a millimeter wave radar installed at the front end of a vehicle, if it is confirmed that the driver is in a distraction driving state and the risk of the collision of the vehicle with the tail of a front vehicle is high, voice early-warning signals are sent out. When the driver does not need to use the sunglasses, the sunglasses can be wirelessly charged on the sunglasses support. The sunglasses have the advantages of simple structure and reliable work. With the sunglasses adopted, the driving distraction problem of a driver wearing sunglasses can be solved.
